I have two Pioneer Elite PD-F19 300 disc CD changers. One is the slave, and one is the Master. The disc titles show up on the Master unit, and a 1/8 inch plug controls the slave transport. However, there is only an analog audio pass-through. I have two digital outs (either coax or optical) that I need to get into one input on my CAL Sigma II. Any ideas?!? Thanks!!

Go to the Audio Authority page at www.audioauthority.com. They have an switcher
with output and 4 or 5 inputs. The inputs are
optical as is the out. Hope this helps.
